VJINDOW-SCREEN.

o all whom it muy Concern.

Be it known that l, lilnNnr C. lVoLr, a citizen of the United States, residing at Catawissa, in the county of Columbia and fit-ate of Pennsylvania, have invented new and useful improvements in lfllindow- Screens, of which the following is a specification.

lhis invention relates to improvements in window screens and particularly to the adinstable type, and the primary object of the invention is to provide a screen mounting or organization which is adapted to be held at any desired location opposite either the upper or the lower portion of the window frame or the upper and lower sash, the screen being guided and held by yielding vertical rods with their lower extremities free or unattached and of less length than the vertical extent of the inside portion of the window frame and permitting the screen to he readily applied or detached. The screen is also constructed with means for adjusting the saine relatively to the width of the inner portion of the window frame and specifically comprises slidable sections with cooperating spring means acting to normally distend the sections and set up a frictional engagement of the outer side edges of the sections with the inner opposite side portions of the window frame.

The invention consists of the construction and arrangement of parts which will be more fully hereinafter described and claimed.

ln the drawing: Figure 1 is an elevation of window frame and sash showing the impro-ved screen organization applied thereto and broken away in part. Fig. 2 is a transverse vertical section on the line 22, Fig. 1, showing a portion of the organization in section. Fig. 3 is an enlarged detail horizontal section on the line 3 3, lig. 1.

The numeral 5 designates a window frame of usual construction having lower and upper sash 6 and 7 respectively movable in grooves 8 and 9 separated by a parting bead 10. 'lfo the inner portion of the top of the frame and beyond the plane of movement of the inner or lower sash 6, resilient guide rods 11 are secured and depend inside the frame to about the distance shown particularly by Fig. 1, the lower extremities of the said rods 11 being free or unattached. 1t will be understood that the rods 11 may be disposed any distance apart or will be arranged proportionately to the width of the opening Specification of Letters Patent.

of the window frame and they may also be lengthened or shortened in accordance with the vertical extent of the said opening. The rods 11 may also be of any suitable gage and will he preferably of a non-corrosive nature.

rlhe screen is composed of two sections 12 and 13 which are slidably associated through the medium of slides so that one section may loe moved over upon or outwardly over the other section to accommodate variations in width of the openings of difl'erent window frames. The sections l2 and .1S have the opposite extremities of an expansion spring 15 in engagement therewith, the inner end of said spring being secured to the section 12 and the outer end curved as at 1G. Along the outer end portions of the screen sections 12 and 13, tubular guides 17 and 18 are mounted and are fully open at their opposite ends, said guides being preferably of metal, and as shown by Fig. E may be formed integral with the end strips 18 of the sections 12 and 13 to simplify the construction and avoid the use of extra pieces for the construction of the said tubular guides. rlhe outer curved end 16 of the spring 15 eX- tends into a slot 19 of the tubular guide 17 and bears against the rod 11 engaging said guide, as clearly shown by lig. 3, and operates to a certain extent to set up a frictional tension between the rod 11 and the guide 17. The primary purpose of the spring 15, however, is to maintain the sections 12 and 13 in laterally distended association so as to cause the outer side edges of the said sections to frictionally bear with such pressure against the side portions of the window frame engaged thereby as to prevent too loose movement of the screen as a whole and prevent the latter from slipping under certain conditions and also to form closed oints between the opposite side edges of the screen sections and the side portions of the window frame.

The screen is freely adjustable to dispose the same either at the lower portion of the window frame, as shown by Fig. 2. or at the upper portion of said frame. l/Vhen the screen is at the lower portion of the window frame and the lower sash 6 is raised, the top of the screen may be pushed under the bottom rail of the lower sash, as shown by Fig. 2, owing to the yielding nature of the rods 11 and thus be held against movement or loose displacement. The screen may be released from the sash 6, as shown by Fig. 2, and said sash lowered and the outer sash also lowered and the screen pushed upwardly to cover the open space formed by the depression or lowered disposition of the upper sash, and in this position the screen may have its lower portion engaged by the top rail of the lower sash to hold the said screen against loose movement and provide a tight joint between the same and the lower sash. The yielding nature of the rods 11 and likewise the collapsible association of the sections 12 and 13 of the screen permit the latter to be readily detached from the rods desired and subsequently mounted in operative position in connection with the rods. lThe latter operation may also be readily accomplished in view of the fact that the lower extremities of the rods are loose or unattached and do not extend fully to the lower or sill portion of the window frame.

It is proposed to make the screen of noncorrosive material and to construct the several parts thereof to the best advantage from a standpoint of economy in manufacture and without in the least detracting from the strength and durability of the same. The improved screen organization will be found exceptionally convenient and it will be observed that the same may be applied in operative position simply by securing the rods ll to the window frame as hereinbefore eX- plained and then associating the screen proper therewith. This manner of mounting the screen in connection with a window frame avoids the necessity of applying extra bead strips or other attachments on opposite sides of the window frame and also permits the screen to be raised to clear the lower sash or lower open portion of the window frame without detaching the screen as in ordinary screen applications, and in addition the upper or lower portion of the window frame may be covered by the screen as may be desired and thus lpermit either the upper or lower sash to be opened for ventilation or other purposes without liability of entrance of insects and without requiring the use of separate screens for the upper and lower portions of the window frame.

lVhat is claimed is:

l. The combination with a window frame and a sash, of yielding rods secured to the upper portion of the frame and depending between the sides of said frame, the lower extremities of the rods being loose, and a screen having means at opposite sides thereof slidably engaging the said rods and also depressible under a portion of the sash.

2. The combination with a window frame and a sash, of yielding rods secured to the upper portion of the frame and loosely depending between the sides of said frame, and a screen having means slidably engaging the said rods and also depressible under a portion of the sash.

3. The combination with a window frame and a sash, of yielding rods secured to the upper portion of the frame and loosely depending between the sides of the frame, and a screen having guide tubes at opposite sides through which the said rods are freely movable.

4. The combination with a window frame and a sash, of yielding means depending from the upper portion of the frame and loosely depending between the sides of the frame, and a screen adjustably engaging the said means and depressible outwardly for engagement by a portion of the sash and operative to close either the lower sash opening or the upper sash opening.

5. The combination with a window frame and sash, of yielding means depending from the upper portion of the frame and having loose lower extremities, and a screen slidably vengaging the said yielding means and comprising adjustable sections engaged by a spring to hold the same distended.

In testimony whereof l have hereunto set my hand in presence of two subscribing witnesses.
